Specification of Letters Patent.

Application filed .Tune 29, 1912. Serial No. 706,726.

T all whom it may concern:

Be it known that I, RnUBnN G. BRUNER, a subject of the Kingof England,residingat Olinda, in the county of Essex `and Province of Ontario,Dominion of Canada, have invented certain new and useful Improvements inl/Veeders, of which the following is a specification, reference beinghad therein to the accompanyingdrawings.

rlhis invention relates to weeders and` more especially to a machine forweeding onions which is adapted to be propelled by hand along a row ofstanding plants and comb out the weeds therefrom and deposit the same atone side of the row.

The invention includes the construction of the weeding members wherebythey may be adjusted for different conditions of service and wherebythey do not become readily clogged. p l

he invention consists in the matters hereinafter set forth and pointedout in the claims.

In the drawings, Figure l is a View, .partially in longitudinalsectlonand partially in elevation of one form of machine that .t ,embodiesfeatures of the invention; Fig. 2

is a view in rear elevation thereof partially broken away; Fig. 3 is aview in detail of a weeding comb; and Fig. 4 is a view showing the combadjusted for a heavy growth.

Referring to the drawings, a main frame `1 of suitable design to combinestrength and lmain shaft 3` through anyl desired connections as forexample, a beveled gear train indicated at 6. p

A spiderl 7 `is adjustably secured on the shaft 5 to turn therewith, asby means of a set screw 8 passing through the spider hub 9 or by othersuitable means. Bracket arms 10 extend from the periphery of the spiderat regular intervals, being` preferably secured thereto by meansaffording longitudinal adjustment.

are adjustably clamped by bolts 12 passing As herein indicated thebrackets lie between parallel lugs 11 and` through slots indicated at`13 in the disk of the spider. The latter may be appropriately ribbed ifdesired, to increase its strength.`

Each bracket has an outer transverse arm lel on which a plurality ofteeth 15 are secured. the latter being bent to partially embrace thebracket and being secured by a clamping plate 1G held by appropriatemeans v such as bolts 17 or the like. The teeth are arranged to be setclose together as in Fig. 3 or disposed in regular intervals as shown inFig. 4L. A stripper in the form of a `fiat strip bent into a closed loop18 is reciprocable longitudinally on the teeth 15 of each comb. A stem20 from each strip is loosely pivoted at its end or otherwisearticulated to one arm 21 of a bell crank lever pivoted on a stud 22 onthe face of the spider 7. The other arm 23 of the bell crank is sodisposed that its extremity encounters a knockofl" bar 2li once duringeach revolution of the spider so that the stripper is `moved to the endof the teeth 15 thereby clearing the comb of weeds or other materialpicked up by the teeth. An appropriately positioned spring 25 returnsthe stripper and bell crank to its initial position.` The knock-offmember 24@ may be situated as desired on the main frame with a view tooperating the strippers at the point desired in their revolution. A pairof runners 26 are formed on the main frame to aid in'supporting andsteadying the machineon the row along which the machine is being moved.

In` operation the machine when made to traverse a row of onions or thelike, rapidly moves the weeding members or combs transversely throughthe row picking up weeds and allowing the onion tops to sliptherethrough.` The strippers throw theweeds off to one side of the row`thereby leaving the latter clear. p

.One feature of the invention is the disposition of the spider thatcarries the weeding members between the end portions of the latter sothat the weeds and other articlesencountered do not tend to becomelodged at the ends of the weeding members as they might if the latterwere mounted on a drum or other device having end supporting members.

Another feature of the invention is the arrangement of the weederswhereby the teethmay be disposed and adjusted to different conditions ofgrowth in the field to be weeded being spaced to allow onion topsv ofany size to pass therethrough without injury while the weeds with leaffoliage or branching stems are pulled away.

The knock-off member may be situated as v desired so that the ejectionof the weeds takes place at any point, each machine be-l the machine iseasily constructed and when ready for the field is not liable to be.injured or thrown out of adjustment.

Obviously, changes in the details of construction may be made withoutdeparting from the spirit of my invention and l do not care to limitmyself to any particulary form or arrangement of parts.

What lf claim is l. ln a weeder a frame, a shaft journaledlongitudinally on the frame, a spider se- Y cured to said shaft, bracketarms on the spider periphery, weeding teeth in adjustable spacedrelation secured on the outer end of each arm, stripping members eachreciprocable on a set of the weeding teeth, means for reciprocating eachstripping member, and a knocknoff member on the frame adapted tointermittently move the reciprocating means.

` 2. In a weeder a frame, a shaft ournaled longitudinally thereon, aspider secured to said shaft, brackets adjustably secured on theperiphery of the spider, stripping teeth in adjustable spaced relationon each bracket, a closed stripper loop embracing I each set of teeth,means on the spider for reciprocating each loop longitudinally of thecompanion teeth, and a knock-oill member adapted to intermittentlyoperate the loop reciprocating means.

3. In a weeder, a spiderl having outstanding .brackets adjustably spacedweeding teeth on each bracket, stripper members each recprocable on theteeth of a bracket, a bell crank for each memberpivoted on the spider, alink articulating each bell crank with a companion stripper member, a

knock-off member in the path of revolution1 of said bell cranks lformoving the latter successively in one direction, and spring means forretracting the bell cranks.

a. In a weeder, a frame, a shaft journaled therein, a spider secured onthe shaft, brackets extending from the spider, weeding teeth secured oneach bracket, a stripping member reciprocable on each set of teeth, abell crank articulated to each stripping member and pivoted on thespider, a knock-off member on the'frame inthe path of revolution of` thebell cranks for moving the latter in @epica mi this patent may beobtained, for

one direction, and spring means for retracting the bell cranks.`

5. In a weeder, a spider rotatable on an axis longitudinally of thelweeder, brackets extending Afrom the periphery of the spider, weedingteeth in adjustable spaced relation on the extremities ofthe brackets,stripper members each reciproca-ble on a set of teeth, a bell crank foreach stripper member pivoted on the spider, a link articulating eachstripper member to va companion bell crank, a knockfoii" member in thepath ofyrevolution of the bell cranks for intermittently moving thevlatter in one direction, and springs normally retracting the bellcranks.

6. In a 'weeder, a spider rotatable on an axisflongitudinally of theweeder, adjustably secured brackets extending from `the periphery of thespider lwith transverse arms on their outer ends, adjustably securedweeding teeth in spaced relationon each transverse arm, a stripper looparound each set of teeth and reciprocable longitudinallythereof,`oscillating members on the spider eachV articulated v,to astripping member to reciprocate the latter, a knock-ofi' member in thepath of revolution of the oscillatory members to intermittently move thelatter in one direction, and springs normally retracting the oscillatingmembers.

7. ln a weeder a shaft, a spider secured on said shaft, weeding teethadjustably secured on the spider periphery, stripper membersreciprocable longitudinallyv of the teeth, 'oscillating membersoperatively articulated to the stripper members andgpivoted on thespider, springs normally retracting the os-` cillating members, andaknock-o' member in thepathl of revolution of the oscillating membersfor intermittently projecting the` cable longitudinally on each vset ofteeth,`

an oscillatory member operatively connected to each stripper member andmounted on the spider, means yieldingly retracting each oscillatorymember, and a knock-olf member in the path of revolution oftheoscillatory members Vfor intermittently projectingl the latter.
